Narrative:Weather conditions deteriorated when the DC-3 approached Hong Kong. The crew decided to divert to Tainan. Tainan however closed down due to bad weather, forcing the Siamese Airways crew to return to Hong Kong. They attempted a night-time visual approach to Kai Tak beneath the 400 feet cloudbase. On approach, the aircraft crashed into the sea.

PROBABLE CAUSE: "The captain allowed the aircraft to lose flying speed while attempting to turn quickly in order to avoid flying into higher ground during the approach to the airport in darkness and rain beneath 400ft cloud base."
